The invention relates to a parallel kinematic device with a fixed platform and with a moving platform based on rods (1, 11, 21, 41) and on actuators, at least one actuator (A, A1, A2) is provided in the form of a rod of a constant length with a foot (6, 16, 26, 46) that can move relative to the fixed platform and, with a rod of a constant length and fixed foot (1, 11, 21, 41) on the fixed platform, comprises a common head (2, 12, 22, 42) on the moving platform, and the retaining force remains largely independent of the angular position of the kinematic. The displaceable foot (6, 16, 26, 46) is guided along an arc of a circle by a steering rod (7, 17, 27, 49) with a fixed foot on the first platform, with which is connected in an articulated manner and it acts upon a point of application (10, 40) connected in a fixed manner thereto via a force introduction element (9, 49). |
